HBO has released the trailer for their upcoming Dr. Dre and Jimmy Iovine documentary, The Defiant Ones. Premiering on July 9, The Defiant Ones focuses on the 25 year relationship between Iovine and Dre. The documentary examines their journey from two completely different backgrounds to building a partnership “that transcended race, age and experience.” Together they not only changed the sound of hip-hop with Dre’s “The Chronic” album, but co-founded one of the most successful audio electronics companies of all time, Beats by Dre. Eventually Beats would be purchased by Apple Inc. for $3 billion in 2014 making it the largest acquisition in Apple’s history. The Defiant Ones includes detailed interviews with the pair as well as Bono, Eminem, Nas, Ice Cube, Gwen Stefani, Tom Petty, Trent Reznor, Snoop Dogg, and Bruce Springsteen.
